1 Claim. (Cl. 215--47) This invention relates to improvements in bottlesand stoppers therefor, one object of the invention being the provisionof a novel form of bottle neck and stopper insertable therein, toprovide a gas tight joint, so that liquids such as carbonated drinks canbe bottled and without leakage of the contents, and one that can bereadily filled, stored and decanted.

Another object of the invention is the provision of a stopper andbottle, whereby male and female portions interlock, the male memberbeing compressible and of a greater cross sectional area than the femaleportion, and also the body of the stopper per se is a tight fit withinthe neck and at the mouth of the bottle.

Still another object of the present invention is the provision of apolyethylene hollow or skirted stopper having a head that provides aguiding means to facilitate the capping of carbonated drink bottles, inthat the head is permitted to be gravity slid between directing rails toa point directly above the awaiting filled bottle, where by a pushingdevice the stopper is forced home with a gastight joint formed thereby.

In order that the invention may be understood and its advantagesappreciated, attention is invited to the accompanying drawings, inwhich:

Figure 1 is a section through the upper end of a bottle neck with thepresent plastic stopper in elevation therein.

Figure 2 is a bottom plan view of the stopper per se.

Figure 3 is an exaggerated sectional view of the portion of the neckwith its receptacle portion and the stopper at the part where theprotuberance is formed thereof.

Referring to the drawings the numeral 8 designates the bottle neckhaving a single annular recess or groove 9, so that when the plasticstopper 10, is forced into the neck, the tight fitting cupped or hollowcylindrical portion is guided by the curved portion 14 of the neck, ismoved until the annular projection 12, is tightly sealed in the groove 9as the projection 12 is of a greater cross sectional area than thegroove or recess, thus providing a gas tight stopper for this type ofbottle.

Also the head of the stopper fits washer tight against the extreme endof the bottle neck, so that no washer or cork disk is necessary, andalso in the capping of the carbonated drink filled bottles, the headacts as a guide to slide by gravity to a point where it is directlyabove the neck of the filled bottle to be easily and quickly driven orpushed home to seal the bottle.

In this instance the hollow or cupped portion 13 permits gas pressurefrom within the container to exert ice pressure to cause the Wall of thestoppers to more tightly fit within the necks of the bottles and alsothe pressing and contracting of the annular projection 12 into theannular recess or groove tends to and does pull the overhanging diskhead of the stopper into closer air or gas tight engagement with theouter face of the neck of the bottle, adding an additional gas-tightnesswhen this invention is used. Also the rim of the said fiat head acts asa suspending guide on the runway used in directing each stopper in placeto be forced into the neck of the bottle. These advantages are veryimportant in a stopper and bottle of this class.

The present objection to using cork, is the inconsistency of theproduct, that is, where it is possible, as in Europe, to permit thebottled wines to age, say for years, a hard cork, will do, but wherethis is impossible, a laminated cork is employed, and this sometimespermits leakage, particularly where carbonated liquids or wines arehottled. This invention, overcomes this, as the particular constructionof a polyethylene stopper, the same is not efiected by the liquid, andwhere gas or liquid leakage is prevented, the desired stopper is had.

With a stopper of this type, the normal crown cork and seal, that is thecrirnped on metal cap, the bottle containing the liquid can be providedwith the internal annular recess, and in which event, the preventplastic stopper can be used as a temporary stopper, after the metal caphas been removed and only a portion of the liquid has been decanted.

What is claimed is:

The combination with a glass bottle to contain gasified liquid and theneck of which is provided with an inner cylindrical stopper receivingsurface terminating at the upper end in an outwardly curved stopperguiding surface, the cylindrical surface having therein an annulargroove spaced inwardly from the upper end thereof, of a plastic stopperhaving a head with an annular flat neck engaging rim contacting theouter end of the neck of the bottle and an inwardly extending hollowopen ended continuous portion cylindrical in shape and snugly receivedin the cylindrical portion of the neck, said cylindrical portion of thestopper having an annular protuberance positioned thereon intermediatethe upper and lower ends of the hollow cylindrical portion thereof, saidprotuberance having a slightly greater cross sectional area than that ofthe groove and fitting therein in tightly compressed sealing relationtherewith and tending when seated to draw and hold the rim contact atthe outer end of the neck of the bottle to form an auxiliary tightgas-tight joint thereat, the cylindrical lower end portion of thestopper acting as a guiding and centering portion as the stopper isforced into the neck of the bottle.
